A sample consisting of `1mol` of a mono-atomic perfect gas `(C_(V) = (3)/(2)R)` is taken through the cycle as shown.

`DeltaU` for the process `(2 rarr 3)` is

A

0.00 J

B

`+3.40` kJ

C

`-3.40` kJ

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
In conversion from state 2 to state 3
`DeltaT = T_(2)-T_(1) = 273-546=-273` K
`C_(v) = 3/2 R`
